"You have been reincarnated as our Dungeon Master. Lure in many adventurers with their desires, and through exploration and combat, create a dungeon that can drain their blood, magic power, and life, Master." One day, a man on the verge of death in a hospital in the modern world hears a strange hallucination. It tells him to operate a dungeon as a Dungeon Master. Faced with this unusually specific hallucination, the man, while lost in fantasies of dungeon management, passes away from his illness.
